A – Wrong
The world must emit less than 1000 gigatonnes of CO2 every year whilst Indonesia only emits 1.6 gigatonnes.
B – Correct
Since the peat is also on fire together with the forests, some CO2 will remain in the atmosphere.
C – Wrong
There is no guarantee that next year will emit more or less CO2 compared to this year. Hence this cannot be concluded.
D – Wrong
There are other ways in which global warming can occur (e.g. burning of fossil fuels). Therefore, only controlling forest fires cannot prevent global warming.
